Vietnam issues detailed rules for its carbon market

Vietnam’s Ministry of Finance has issued Circular No. 48/2026/TT-BTC, laying out detailed rules for supervising the trading of greenhouse-gas emission allowances and carbon credits. It is a technical document, but a meaningful one: it is the kind of plumbing a country needs before a real carbon market can run.

For communicators, the significance is less the circular itself than the trend it represents. A growing list of emerging economies are building Cap and Trade-style systems and rules to govern Carbon Offsets, rather than leaving carbon pricing to wealthy blocs like the EU. As more national markets come online, the question of how credits move between countries gets sharper — which is where Article 6 of the Paris Agreement, the mechanism for cross-border carbon trading, comes in.

The practical takeaway: if your organisation operates in or sources from Southeast Asia, carbon-market compliance is shifting from “future risk” to “live regulatory detail.” Claims about offsetting or carbon neutrality made in these markets will increasingly be measured against actual national rules, not voluntary-market norms.
